Abstract
The utility model relates to a middle groove of a rear scraper conveyer capable of being turned for use; the middle groove comprises three parts, i.e. a middle groove body (1), a shovel pulling connecting piece (2) and a coal placing body (3); and the three parts are in a split structure. The middle groove body is hinged with the shovel pulling connecting piece and the coal placing body respectively through horizontal pin shafts (4). The middle groove body (1) is of a whole welding structure with the left part and the right part being symmetric. A wear-resistant layer (5) is arranged on the inner surface of the middle groove body (1). The middle groove is used for the rear scraper conveyer on the fully mechanized top coal caving face of a coal mine, and can be conveniently turned for use, transportation by fully utilizing the upper and the lower planes and two groove sides of the middle groove can be realized, and the service life of the middle groove is further improved and the use cost is reduced through the wear-resistant layer which is arranged on the inner surface of the middle groove.
Description
Technical field
The utility model relates to coal mine fully-mechanized mining transportation device slat conveyer, particularly a kind of rear portion the middle pan of scraper conveyor of the turning use for comprehensive extracting and caving face rear portion slat conveyer.
Background technology
At present, the intermediate channel of comprehensive extracting and caving face rear portion heavy scraper conveyor under the coal mine generally adopts asymmetric integral solder structure, after join and put coal body.This structure can guarantee that intermediate channel has higher structural strength, is easy to processing and manufacturing.But, if want to melt on the chute surface service life of attached antifriction metal (AFM) coating, raising intermediate channel, the use of can not overturning of asymmetric integrally-built intermediate channel also just can't take full advantage of two planes of plate in the intermediate channel and service life that two trough rims transportations further improve intermediate channel, reduce use costs.
Summary of the invention
The deficiency that can not overturn and use in order to overcome the existing integrally-built intermediate channel of fully mechanized coal face rear portion slat conveyer, the utility model provides a kind of rear portion the middle pan of scraper conveyor of turning use, can upset use, take full advantage of upper and lower two planes and two the trough rim transportations of plate in the intermediate channel, further improve service life, the reduction use cost of intermediate channel.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to be:
The rear portion the middle pan of scraper conveyor of turning use is drawn attaching parts and is put coal body etc. by intermediate channel cell body, shovel and consists of.Intermediate channel cell body, shovel draw attaching parts, put the coal body three is split-type structural.Intermediate channel cell body and shovel draw attaching parts, it is hinged by horizontal bearing pin respectively to put between the coal body.The intermediate channel cell body is left-right symmetric integral solder structure.The inner face of intermediate channel cell body is lined with wearing layer.
The beneficial effects of the utility model are:
This rear portion the middle pan of scraper conveyor can spin upside down use easily, can utilize upper and lower two planes of plate in the intermediate channel and two trough rim transportations of intermediate channel, in the service life of further improving intermediate channel, reduces use cost.
Description of drawings
Fig. 1 is the structural representation shaft side figure of the rear portion the middle pan of scraper conveyor of turning use.
Fig. 2 is the structural representation shaft side figure of intermediate channel cell body.
Fig. 3 is the structural representation front view of the rear portion the middle pan of scraper conveyor of turning use.
Among the figure: 1-intermediate channel cell body, 2-shovel draw attaching parts, 3-to put coal body, the horizontal bearing pin of 4-, 5-wearing layer.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Formation in the rear portion the middle pan of scraper conveyor of the turning use of the utility model shown in Fig. 1,3.This rear portion the middle pan of scraper conveyor is mainly drawn attaching parts 2 and is put coal body 3 and formed by intermediate channel cell body 1, shovel.Intermediate channel cell body 1, shovel draw attaching parts 2, put coal body 3 threes is split-type structural.Intermediate channel cell body 1 and shovel draw attaching parts 2, put between the coal body 3, and be hinged by horizontal bearing pin 4 respectively.Intermediate channel cell body 1 is left-right symmetric integral solder structure.The inner face of intermediate channel cell body 1 is lined with wearing layer 5, and its material is NiCrFeBSi alloy and CoCrWB alloy; Perhaps two kinds of alloys adopt separately.
Wearing layer can improve the service life of intermediate channel cell body effectively.Be arranged in first when using in the fully mechanized coal face at the rear portion slat conveyer, larger operation friction is born on above the plate and lower edge in its intermediate channel cell body, has than galling.Change in face or the intermediate channel cell body above the plate and lower when more serious along wearing and tearing in fully mechanized coal face removal of home, with intermediate channel cell body 1 and shovel draw attaching parts 2, the horizontal bearing pin 4 of putting coal body 3 disassembles.Then, intermediate channel cell body 1 is spun upside down 180 °, again shovel drawn attaching parts 2, put coal body 3 and again connect with the horizontal bearing pin 4 of intermediate channel cell body 1 usefulness.
The structure of intermediate channel cell body 1 of the present utility model shown in Figure 2.Intermediate channel cell body 1 is left-right symmetric integral solder structure.The two ledges outside is welded with axis pin base about intermediate channel cell body 1, is used for installing horizontal bearing pin 4.
Claims (2)
1. the rear portion the middle pan of scraper conveyor of a turning use, comprise that intermediate channel cell body, shovel draw attaching parts and put coal body, is characterized in that: said intermediate channel cell body (1), shovel draw attaching parts (2), put coal body (3) three is split-type structural; Intermediate channel cell body (1) and shovel draw attaching parts (2), it is hinged by horizontal bearing pin (4) respectively to put between the coal body (3); Intermediate channel cell body (1) is left-right symmetric integral solder structure; The inner face of intermediate channel cell body (1) is lined with wearing layer (5).
2. the rear portion the middle pan of scraper conveyor of turning use according to claim 1, it is characterized in that: the material of said wearing layer (5) is that NiCrFeBSi is or/and the CoCrWB alloy.
